  1. Chapter 1- Motion How can an objects motion be described?

  2. April 21, 2014- Welcome Back! • Homework: Finish, “What I Learned,” List Started in class in notebook. Read pgs. 7-11 in textbook • Do Now: Write down homework, Open textbook to pg. 6 • Update TOC: pg. 20- Chapter 1-Motion Title page Pg. 21- Describing Motion

  3. Motion- What do you know about Motion? • What I know: • An object is moving when it changes position • Objects move at different speeds • This effects how long it takes for an object to travel a certain distance..

  4. Describing Motion-Read pg.6 • Motion- An object is in motion if its distance from another object is changing. • Reference point- is a place or object used for comparison to determine is something is in motion. • An object is in motion if it changes position relative to a reference point.

  5. Moving or Not Moving?? • Are students on a bus moving compared to a person standing on the side walk? Why? • Yes, because the distance between the students and the person on the sidewalk is changing • Are the students seated on the bus moving compared to the bus? Why? • No, because the distance between the bus and the students does not change.

  6. What makes a good reference point? • Objects that are stationary, (not moving). • Examples:

  7. Why is it important to chose a stationary object as a reference point? • If you choose a moving reference point, • You may think that you are moving when you are not • Or that you are moving faster or slower than you really are. Read over pg. 7 to pg. 8

  8. What I learned…. (pages 7-9) • Something I learned about motion • Another thing I learned about motion • One more thing I learned about motion

  9. April 22, 2014 • Homework:Speed worksheet. • Do Now:Write down homework, • Update TOC : pg. 22- Calculating speed • Open textbook to pages 10 & 11: • Then Define: all highlighted terms and write the speed equation, on pg. 22 • Today I will Calculate an objects speed

  10. What I learned… • To measure distance the SI unit used is for length is meter (m). • Motion is compared to a reference point

  11. Speed: • The distance an object travels per unit of time. • If you know the distance an object travels in a certain amount of time you can calculate the speed

  12. Calculating Speed • Speed = Distance/ Time What is the Speed of a asteroidtraveling 4500km in 6 seconds? • What are two ways to increase this speed? • Increase the distance • Decrease the time

  13. Avg. Speed and Instantaneous Speed • Average Speed: The total distance divided by the total time • Instantaneous Speed: The rate that an object is moving at a given instant of time.
